Cloud 未接收来自GCM服务器的消息

我正在根据此处和此处提供的示例创建GCM客户端。基本上，它只做第一个示例所做的，但我将其更新为使用GoogleCloudMessaing API

作为服务器，我使用了第一个链接中使用的示例php服务器。但是当我通过php脚本发送消息时，我的设备上没有收到任何消息

在服务器端，我使用mysql密码和GoogleAPI密钥修改了config.php文件

    ?php
    /**
      * Database config variables
    /
   define("DB_HOST", "localhost");
   define("DB_USER", "root");
   define("DB_PASSWORD", "password");
   define("DB_DATABASE", "gcm");

  /*
   * Google API Key
   */
   define("GOOGLE_API_KEY", "MY GOOGLE API KEY"); // Place your Google API Key

我在gcm_users表中手动创建了一个条目，这样我就不必从我的应用程序发送注册ID。该表包含第一个链接中提到的regId、name和email

然后，我从index.php页面发送了一条消息，但从未收到该消息

我的android清单文件-

}

我已验证我已在gcm服务器上正确注册，并且服务器将注册id返回到我的应用程序。此RegisterActivity.java文件的主要部分：

    package com.example.gcmclient;

    import android.app.IntentService;
    import android.content.Intent;
    import android.os.Bundle;

    import com.google.android.gms.gcm.GoogleCloudMessaging;

    public class GCMIntentService extends IntentService {
public GCMIntentService() {
    super("GCMIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);

    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that GCM will be
             * extended in the future with new message types, just ignore any message types you're
             * not interested in, or that you don't recognize.
             */
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            Utilities.showNotification(this, "Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            Utilities.showNotification(this, "Deleted messages on server: " + extras.toString());
            // If it's a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            Utilities.showNotification(this, "Received: " + extras.toString());
        }
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GCMBroadcastReceiver.completeWakefulIntent(intent);
    }
}

    private void registerInBackground() {
    new AsyncTask<Void, Void, String>() {
        private Random mRandom = new Random();

            return msg;
        }

Apache日志显示来自index.php的原始发送请求的状态ok（200）
